I've never used the plugin myself, but I hear it works. I use a language instead (Arabic) so I get a full sense of the differences, but it's not necessary. I think azaozz may have a patch almost ready, though.

Is it just me or the menu icons are a bit lower when the menu is folded?

azaozz, it isn't just you. But your browser must be narrow enough to trigger the auto-fold. If your window gets just wide enough to stop auto-folding but you still have it collapsed, the collapsed menu will shrink slightly in height.
